Did Britney Spears really scream and shout on her new track with will.i.am?

On Wednesday night's "Watch What Happens Live" on Bravo, host Andy Cohen asked his guests Eve and English celeb chef Nigella Lawson their feelings about the pop star's British accent in her collaboration with the Black Eyed Peas' frontman.

"I heard that might not be Britney," the rapper-designer interjected, making a face.

As massive boos rained down on her from the audience, Eve playfully covered her face and then her butt. (Watch the video HERE)

"That's what I heard, but you know, I don't know," she continued. "It could be Britney. But I heard it wasn't"
